Abstract： Radiotherapy is the main and effective treatment for nasopharyngeal carcinoma(NPC).Reliable prediction of tumor treatment efficacy before radiotherapy can significantly optimize the treatment plans for NPC patients and prolong their survival time.Intravoxel incoherent motion(IVIM)and dynamic contrast-enhanced MRI(DCE-MRI)can provide multiple indicators to quantitatively describe the diffusion of water molecules and microcirculation perfusion information of tissue,which reflect the pathological changes of the lesion microscopically,and thereby contribute to the prediction of tumor treatment efficacy.The radiomics developed on them further improves the accuracy of prediction.We briefly introduced IVIM and DCE-MRI techniques,and focused on the current research status of these two MRI imaging features and related radiomics for predicting the treatment efficacy of NPC,as well as the main limitations and future research directions of each technology in clinical practice.Exploring the potential imaging biomarkers,IVIM and DCE-MRI will provide an objective foundation for personalized treatment and improve patient prognosis in the future.
